Week of September 17 - September 23, 2012
Along with changes to the code itself, the Rails Guides have now been converted from Textile to Markdown. As someone who had to work with the Textile version in the past I'm quite happy with this.
- The new ruby template handler extension has changed from .rb to .ruby as of de1060f4, to avoid conflicts with mustache views.
- As of c49d959e the code from strong_parameters is integrated directly into Rails. All Action Controller parameters must now be explicitly permitted before they can be used in Active Model mass assignments.
- As of 392eeecc Rails allows specifying the transaction isolation level in Active Record (if your database supports it).
- It's an early draft, but the Rails 4.0 Release Notes are now on the Edge Guides site.
